H. M. HART ET AL DOOR HANDLE AND THE LIKE Filed Jan. 22, 1936 Patented May 11, 1937 DOOR HANDLE AND THE LIKE Henry Morris Hart and Hector Raymond Hart, Durban, and Edward Hector Lonsdale Hart, Johannesburg, Union of South Africa Application January 22, 1936, Serial No. 60,298 In the Union of South Africa November 13,

1 kThis invention relates to door handles and the The object of the invention is to produce door handles having means for securing the same in position to the door, which will allow of such handles being used with varying thicknesses of doors, and to accomplish this purpose by a simple, efficient and comparatively inexpensive construction which can be easily and quickly arranged and secured in operative position.

This object is attained by means which obviate the necessity for providing the spindle on which the handles are operatively arranged with a screw-thread or threads, or with grooves, or holes or recesses for fixing screws, thereby avoiding the difficulty in adjusting existing handles by such means, and the other drawbacks appertaining thereto.

The handle for each side of the door may be made of any desired shape, and of any suitable metal or material, such as reinforced bakelite or synthetic resin. Each handle portion is rotatably arranged in a rose or relatively stationary part, which is fixed to the door. For this purpose said rose may be provided with a suitable number of holes for the screws fixing it to the door, and be provided with a boss to afford sufficient bearing for the handle to rotate in. The rose may be constructed on the side next the door with a recess, and if made of bakelite or similar material, a suitable metal washer or plate will be seated within said recess and formed with holes coincident with the holes for the fixing screws in the rose, so that said screws will serve for nonrotatably retaining the washer or plate in position.

According to the invention each handle portion is provided with a spindle projecting for a suitable short distance beyond the inner face of the rose. These spindles are of square or any other non-circular shape in cross-section, and are secured in position and rotatably retained in the rose by any suitable means, such as a split pin. The inwardly projecting non-circular spindle portions of the handles in the door are rotatably connected together by means of a sleeve or ferrule of corresponding non-circular shape, or otherwise shaped interiorly non-rotatably to receive the inwardly projecting spindle portions of the handles. riorly operatively to engage with the means for operating the catch, latch, bolt, or other doorretaining or locking means or device.

Instead of constructing the sleeve or ferrule of square or other non-circular internalshape to fit 2 Claims. (01. zest-sis),

The sleeve or ferrule is shaped exte over the correspondingly shaped ends of the projectingspindle portions, as above described, the latter maybe made hollow and of square or other non-circular shape :in cross-section internally, and the sleeve or connecting piece be shaped to project into and fit the spindle ends.

The handles may, if required, be reinforced by constructing the spindle portions of suitable length to extend into and be embedded in the bakelite or similar handle for any suitable dis- 10 tance.

The invention will be further explained with the aid of the accompanying sheet of drawing, wherein Fig. 1 is a part-sectional elevation of the two handles and the sleeve or connecting means; portion of the door frame, the lock casing, and. that element of the 100 which is mounted on the sleeve or connecting means and functions to operate the catch or retaining means, being shown in dotted lines, and

Fig. 2 is a section through the sleeve or connecting means, showing the rose and one handle as seen from the inside.

In Fig. 1, the numerals I, 2, denote the handles which may be constructed of bakelite or any other suitable material, and be of the shape shown or any other suitable shape.

3 and 4 are the roses, which are secured to the door 5 by means of screws screwed through countersunk holes 6 in the roses into the door 5. The roses 3, 4, as usual, are constructed with hollow bosses 1 in which are rotatably arranged the inner cylindrical end portions 8 of the handles I, 2.

9 are the short projecting spindles. Each pro- 33 jecting spindle 9 is a portion of a bar 10, which extends into the handle to a point ll near the outer end thereof, and serves as the means for reinforcing the bakelite or similar material of the handle.

Each rose 3 or 4, in the inside, is recessed as indicated at [2, and in said recess I2 is arranged a metal washer or plate l3, which is fashioned with a hole M the diameter of which is sufiicient to allow the spindle 9 to rotate therein whilst affording it a bearing at the corners. The washer or plate I3 is provided with holes I5 which coincide with the holes 6 in the rose, and it is secured to the rose by means of the screws which are placed in said holes 6.

Each handle is rotatably retained in position by meansof a split pin I6 which projects through a hole H in the squared spindle portion 9 and engages with the inner face of the washer or 55 plate [3. As shown in Fig. 2 the split pin I6 is bent so as to prevent its disengagement from the spindle portion 9.

i8 is the sleeve, ferrule or connecting piece which is shown made of internal and external square shape in cross-section. The spindles 9, when the handles l, 2, are in position, project for some distance into the sleeve l8, so that they cannot rotate therein, and so that the rotary movement of either handle is communicated to the other through the sleeve l8.

l9 represents the lever or that part of the catch operating means which is arranged on the sleeve I8 and is of square internal shape to fit the latter. 20 is the lock casing fitted in the door 5.

It will be evident that by connectingthe spindle portions 9 of the handles I, 2, by means of the sleeve l8, the arrangement can be adopted for doors of different thickness, and that the necessity for any careful adjustment of the parts in fixing the handles I, 2, to the door 5 is obviated.

What we claim as our invention and desire to protect by Letters Patent is:

1. In door handles, in combination, a pair of handles each constructed with an inwardly projecting spindle portion of non-circular shape in cross-section, means for rotatably attaching said handles to opposite sides of the door, and a hollow connecting piece of the same shape internally as the spindles are externally, which is positioned between the handles and is slidably and non-rotatably engaged by the inwardly projecting spindle portions, as set forth.

2. In door handles, in combination, a pair of handles each constructed with an inwardly projecting spindle portion of square shape in crosssection, means for rotatably attaching said handles to opposite sides of the door, and a loose sleeve of square shape internally positioned between the handles and non-rotatably and slidably engaged by the inwardly projecting spindle portions, as set forth.
